Force of attraction and repulsion equal?

Force of attraction and repulsion equal?

Force of attraction and repulsion equal?

(OP)
I've been doing some searching and I've found some information that seems to suggest that magnets exert a slightly higher attractive force than their repulsive force, when dealing with two identical magnets.  For example, two magnets placed N to S would exert more force on each other (attractive) than the same magnets placed N to N or S to S (repulsive) at the same distance of separation.  The difference is supposedly very slight, and decreasing as distance increase.  Can anyone confirm this?  

Here is the link to the information:

I'm new to studying magnets, so please forgive my lack of knowledge on this subject.

RE: Force of attraction and repulsion equal?

It is completely obvious that attractive and repulsive forces as you state them are not equal. Those forces may be interpreted as a result of change of magnetic energy stored in the system when the distance between the magnets changes by an infinitesimal quantity. Now the magnetic energy is related to the pattern of the induction flow, and this is different, not simply symmetrical, when polarities oppose or concur.

RE: Force of attraction and repulsion equal?

Since the flux distribution are different I would expect the forces to be different.  The difference should also depend on the size/shape of the magnets.
